Testimonials

I started working with ASSC in 2015. I was facing a nine-unit replacement at one of my commercial buildings in Danville. I noticed several ASSC vans and crew members working at a neighboring building and decided to call them for a quote. They were very responsive and competitively priced. I decided to go with them, I am so glad I did!

That job went very well, and since then, they have taken over the majority of the buildings within my portfolio. I rely on them for quarterly preventative maintenance, service calls, and replacements when needed. I have been nothing but delighted with their service, professionalism, turnaround time, and overall quality of their work!

Their team of skilled technicians and office staff are very knowledgeable and are always willing to educate me and answer all my questions. They know my properties as intimately as I do. As a property manager, having reliable vendors that you can trust to perform necessary work is critical, but having a vendor that takes as much pride in your buildings as you do is rare and extremely valuable, and that is precisely what Team ASSC does.

Air Systems Service and Construction has been a great partner to work with. They listen to our needs and offer realistic solutions. They think outside of the box and tailor the solution to the situation and the client – not just proposing the most expensive option. I wouldn’t hesitate to recommend their services.

- Susan J. Louie, General Manager, Newmark Knight Frank

McCuen Properties and Air Systems Service and Construction have been working together since 1998. We know we can depend on ASSC to complete work with quality workmanship and always on or under budget. Through the design build construction of our office buildings to the servicing all of our management accounts, ASSC has been a vital part of our success. We look forward to many more years of partnership.

- Mary Leonard, Vice President Property and Facilities Management, McCuen Properties

From the very beginning, the project team was very collaborative, committed to utilizing lean techniques and agreed to focus on the greater good of the project rather than individual company interests

As a result of the team being so collaborative and innovative, 2020 Gateway Tower was built without any change orders due to the missed scope or design discrepancies

In the design and construction of the building’s plumbing and mechanical systems, ASSC embraced lean construction methods, took a very creative and collaborative approach, stayed within budget and exceeded our expectations by helping us achieve LEED Gold Certification.

- Jennifer Lauritzen, Sr. Project Manager, HMH Builders

The assigned ASSC technicians have good skills and always do what’s necessary to maintain this critical facility. When it breaks, it gets fixed! The company is deep in terms of technical expertise and the ability to design solutions, all backed  with fabrication support back in the shop.”

I have worked with ASSC for many years to keep our data center operating efficiently to serve the needs of Sutter Health’s medical facilities. I would recommend ASSC for preventive maintenance, repair service, design, fabrication, construction, testing controls, and commissioning. I appreciate that I have an advocate within ASSC who works with me directly to assure the smooth operation of our data  center’s cooling systems.

- John Dennis, Data Center Facilities Engineer, Sutter Health

ASSC provided input on the design drawings, solidified the process for coordination  and was innovative in helping us resolve multiple issues as we built the laboratory.

Our schedule was aggressive and ASSC was flexible in working with other contractors to get the job done. When we ran into a challenge, they dedicated resources and  technical expertise to find solutions that fit within the budget.

They were a vital part of our team and helped us achieve success on this project.
